Description

Technical Field

[0001] This invention relates to the field of crystalline silicon cell manufacturing technology, and in particular to a high-precision multi-dimensional basket positioning sensing component. Background Technology

[0002] With the rapid development of the domestic solar cell industry, the requirements for processing silicon wafers are becoming increasingly stringent, and contactless processing is becoming the mainstream. Therefore, fully automated silicon wafer loading machines have emerged. Practice has proven that they effectively improve production efficiency, reduce manual contact with silicon wafers, avoid contamination caused by human factors, effectively increase yield and conversion rate, and reduce labor costs. The entire process only requires periodic replacement of the special loading baskets, creating considerable economic benefits.

[0003] The wafer tray is a device used to carry monocrystalline and polycrystalline silicon wafers and complete the conversion, cleaning, and drying processes of the silicon wafers. It has a hollow bottom. The wafer guide machine is a multi-functional tooling conversion device that guides, inserts, and stacks wafers from the wafer tray or stacking box to the wafer tray and stacking fixture. Generally, the wafer guide machine needs a sensor on the wafer tray transport line to detect the position of the wafer tray, thereby driving the machine to take the next action on the wafer tray.

[0004] In existing technologies, diffuse reflection photoelectric sensors are typically installed at designated locations on the wafer guide machine to detect the arrival of the basket. However, due to the reflective properties of some materials used in the basket and the silicon wafer, the diffuse reflection photoelectric sensors often fail to accurately detect the arrival of the basket, thus affecting the safe production of silicon wafers. Furthermore, since the conveyor belt of the wafer guide machine is still running while the sensing component is sending a command to the arrival switch, the arrival position of the basket may still deviate significantly after the sensing component detects that the basket has arrived, making it impossible to ensure the accurate arrival of the basket.

[0005] Therefore, in order to address the aforementioned technical issues, it is necessary to provide a high-precision multi-dimensional basket positioning sensing component. Summary of the Invention

[0032] The specific embodiments of the present invention will now be described in detail with reference to the accompanying drawings, but it should be understood that the scope of protection of the present invention is not limited to the specific embodiments.

[0033] Unless otherwise expressly stated, throughout the specification and claims, the term "comprising" or its variations such as "including" or "comprises" shall be understood to include the stated elements or components without excluding other elements or other components.

[0034] The high-precision multi-dimensional flower basket positioning sensing component includes a main control box 8, a through-beam photoelectric sensor component, a passive radiation sensor component, and a physical sensing sensor component. The main control box 8 is used to receive the conversion signal emitted by the positioning sensing component.

[0035] The flower basket includes an upper cover plate, a lower cover plate, and a connecting support frame. The connecting support frame is fixedly connected between the upper and lower cover plates. The through-beam photoelectric sensor assembly can sense the position of the connecting support frame. The through-beam photoelectric sensor assembly can only sense the connecting support frame of the flower basket and cannot sense the upper and lower cover plates.

[0036] The through-beam photoelectric sensor assembly, the passive radiation sensor assembly, and the physical sensing sensor assembly are all connected to the main control box 8 and can transmit conversion signals to the main control box 8. The connection method between the through-beam photoelectric sensor assembly, the passive radiation sensor assembly, and the physical sensing sensor assembly and the main control box 8 is one or a combination of wired or wireless connection.

[0037] Specifically, in complex environments, the cables used for wired connections are often intertwined, making them easy to become tangled and difficult to organize and manage. Cable routing and maintenance are also very challenging. Therefore, wireless connection is the preferred method for connecting the photoelectric sensor components, passive radiation sensor components, and physical induction sensor components to the main control box 8.

[0038] In addition, in simple environments, the laying and storage of cables are relatively easy, and there are not many problems with inspection and maintenance. Therefore, it is still preferable to choose wired connection methods that have more stable and reliable connection signals and are less affected by environmental interference to ensure the accuracy of sensing.

[0039] The through-beam photoelectric sensor assembly includes a through-beam photoelectric emitter 7 and a through-beam photoelectric receiver 13, which are symmetrically arranged and matched. Under normal conditions, the infrared photoelectric emitted by the through-beam photoelectric emitter 7 can be received by the through-beam photoelectric receiver 13.

[0040] Specifically, when the flower basket arrives, the connecting support frame of the flower basket will block the infrared photoelectric sensor, causing the infrared photoelectric sensor emitted by the emitter to be unable to be received by the receiver. At this time, the conversion circuit inside the receiver will generate an electrical signal and send it to the main control box 8 to realize the arrival sensing of the flower basket.

[0041] The passive radiation sensor assembly includes a passive radiation sensor 10, which is vertically arranged. The movement path of the flower basket passes directly above the passive radiation sensor 10, which is capable of sensing the position of the lower cover of the flower basket.

[0042] Specifically, when the flower basket arrives, the lower cover of the flower basket is directly above the passive radiation sensor 10, which causes changes in the absorption and backscattering of the rays emitted by the passive radiation sensor 10. At this time, the conversion circuit inside the passive radiation sensor 10 will convert the signal and send it to the main control box 8 to realize the arrival detection of the flower basket.

[0043] The physical sensing sensor assembly includes a pressure sensor 15 and a pressure-receiving component, which is capable of transmitting pressure to the pressure sensor 15; the pressure-receiving component is mounted on the pressure sensor 15, and the flower basket can indirectly apply pressure to the pressure sensor 15 through the pressure-receiving component.

[0044] The pressure-bearing component can come into direct or indirect contact with the flower basket. The pressure-bearing component is made of nylon, plastic, or other lightweight polymer materials. In this embodiment, nylon is preferably chosen as the pressure-bearing component because its light weight has minimal impact on pressure sensing, and it will not damage the flower basket when in direct contact.

[0045] Specifically, when the flower basket applies pressure directly or indirectly to the pressure-receiving component, the pressure-receiving component will apply the pressure to the pressure sensor 15. After the pressure sensor 15 senses the change in pressure, the conversion circuit will also generate an electrical signal and send it to the main control box 8 to realize the arrival sensing of the flower basket.

[0046] It is worth noting that among the three methods of flower basket positioning, the through-beam photoelectric sensor has the highest accuracy and the lowest failure rate. The other two methods, when combined with the through-beam photoelectric sensor, can also achieve very accurate positioning of the flower basket.

[0047] When the through-beam photoelectric sensor assembly and the passive radiation sensor assembly are used together, they can perform multi-dimensional positioning sensing of the flower basket in both horizontal and vertical directions. When the through-beam photoelectric sensor assembly and the physical sensing sensor assembly are used together, they can perform positioning sensing of the flower basket by combining photoelectric and physical methods. The combination of the two methods can achieve accurate positioning sensing of the flower basket.

[0048] In addition, when the opposed photoelectric sensor assembly, passive radiation sensor assembly, and physical induction sensor assembly work simultaneously, they can perform multi-dimensional and physical object combination in-place sensing on the flower basket. This combined in-place sensing method has the highest progress rate and the lowest error rate. Under specific conditions, such as when the equipment is old and there are many surrounding environmental interference conditions, the in-place sensing using this combined method is the best.

[0049] A pre-sensing component is provided on one side of the opposed photoelectric sensor. The pre-sensing component includes a diffuse reflection photoelectric sensor 12. The diffuse reflection photoelectric sensor 12 is at the same horizontal plane as the opposed photoelectric sensor. The connection method between the pre-sensing component and the main control box 8 is one or a combination of two of wired connection or wireless connection.

[0050] Specifically, the pre-sensing component is used to sense the approaching flower basket before it arrives. After the electrical signal of the pre-sensing is sent to the main control box 8, preparatory measures can be taken for the in-place sensing of the flower basket, such as changing the operation mode and operation speed of the equipment.

[0051] Taking the film guiding machine as an example, as Figures 1 to 7 shown, the film guiding machine can guide, insert, and stack films from the flower basket or stacking box to the flower basket and stacking tooling. The film guiding machine includes a main body frame 1, and a transmission component is installed on the main body frame 1. The transmission component is used for conveying the flower basket.

[0052] Refer Figure 1 and Figure 2 shown, the transmission component includes a driving motor 2, a transmission shaft 3, and a conveyor belt 4. There are two groups of transmission shafts 3 rotatably connected to the main body frame 1. Both sides of the main body frame 1 respectively have frames for assembling the transmission shaft 3, and bearings are symmetrically installed on the frames. The two ends of the transmission shaft 3 are respectively inserted into the interior of the bearings, thereby realizing the rotational connection of the transmission shaft 3 inside the bearings.

[0053] Refer Figure 1 and Figure 2 shown, the conveyor belt 4 is arranged outside the two groups of transmission shafts 3. Among them, two groups of rollers for assembling the conveyor belt 4 are installed on each group of transmission shafts 3, and a conveyor belt 4 is arranged between the two groups of rollers on the two groups of transmission shafts 3 for stable transmission of the flower basket. The driving motor 2 is fixedly connected to the main body frame 1, and the power shaft of the driving motor 2 is fixedly connected to the transmission shaft 3 through a coupling. The driving motor 2 can be installed on any one of the frames on both sides of the main body frame 1, and the driving motor 2 can drive any one of the transmission shafts 3 on the main body frame 1 to rotate. The specific model of the driving motor 2 can be ZDY218.

[0054] Specifically, refer Figure 1As shown, when the drive motor 2 drives any set of drive shafts 3 to rotate, it can drive two conveyor belts 4 to operate, enabling the flower basket to be conveyed to the designated position on the conveyor belt 4.

[0055] Refer Figure 1 and Figure 2 As shown, the main control box 8 is installed on the main body frame 1, and the operation, start, and stop of the transmission component are controlled through the main control box 8. An electrical connection is formed between the drive motor 2 and the main control box 8 through a wire. The main control box 8 serves as a position switch. It can not only control the operating power of the drive motor 2 in a variable frequency manner to adjust the running speed of the conveyor belt 4, but also act as a switch for the drive motor 2 to control the start and stop of the conveyor belt 4. It is the "brain" for the flower basket position induction.

[0056] Refer Figures 1-6 As shown, the multi-dimensional position induction component includes an opposed photoelectric sensor, a passive radiation sensor 10, and a physical induction sensor component, which can perform multi-dimensional position induction on the flower basket. The opposed photoelectric sensor includes an opposed photoelectric emitter 7 and an opposed photoelectric receiver 13. The opposed photoelectric emitter 7 is fixedly connected to the first vertical plate 6, and the opposed photoelectric receiver 13 is fixedly connected to the second vertical plate 9. The opposed photoelectric emitter 7 and the opposed photoelectric receiver 13 are matched. Here, the opposed photoelectric emitter 7 and the opposed photoelectric receiver 13 are at the same height in the same vertical plane, and the photoelectric signal emitted by the opposed photoelectric emitter 7 can be exactly received by the opposed photoelectric receiver 13.

[0057] Specifically, refer Figure 1 and Figure 2 As shown, when the flower basket on the conveyor belt 4 is not in place, there is no obstacle between the opposed photoelectric emitter 7 and the opposed photoelectric receiver 13, and the photoelectric emitted by the opposed photoelectric emitter 7 can be normally received by the opposed photoelectric receiver 13. At this time, the conveyor belt 4 is always in operation. When the flower basket on the conveyor belt 4 is conveyed between the opposed photoelectric emitter 7 and the opposed photoelectric receiver 13, it will form an occlusion between the opposed photoelectric emitter 7 and the opposed photoelectric receiver 13, making the photoelectric emitted by the opposed photoelectric emitter 7 unable to be normally received by the opposed photoelectric receiver 13. At this time, the conversion circuit inside the opposed photoelectric receiver 13 will immediately send a signal to the main control box 8. When the main control box 8 receives this signal, it controls the drive motor 2 to stop working, thereby stopping the operation of the conveyor belt 4, and further stopping the flower basket position induction, waiting for the machine to perform the next action on the flower basket.

[0058] Refer Figure 1 、 Figure 4 and Figure 5As shown in the figure, a cross beam 5 is fixedly connected inside the main body frame 1, and the passive radiation sensor 10 is fixedly connected to the cross beam 5. The passive radiation sensor 10 is located at the middle position on the cross beam 5, and its ray emitting end faces vertically upward. By the different absorption and backscattering effects of different substances on the rays emitted by the passive radiation sensor 10, it is judged whether the flower basket on the conveyor belt 4 is in place.

[0059] Specifically, referring to Figure 1 As shown in the figure, when the flower basket on the conveyor belt 4 passes above the cross beam 5, due to the change of substances, the absorption and backscattering effects on the rays emitted by the passive radiation sensor 10 change. At this time, the conversion circuit inside the passive radiation sensor 10 will convert this signal and send it to the main control box 8, so that the main control box 8 controls the drive motor 2 to stop working, thereby stopping the conveyor belt 4 from running, so as to achieve the in-place induction stop of the flower basket.

[0060] Referring to Figure 1 、 Figure 4 and Figure 5 As shown in the figure, the physical induction sensor assembly includes a pressure sensor 15, a bracket 16 and a movable roller 17. Two groups of pressure sensors 15 are fixedly connected to the cross beam 5, and a pressure-receiving component is installed on the pressure sensor 15. The pressure-receiving component includes a bracket 16 and a movable roller 17. The bracket 16 is fixedly connected to the pressure sensor 15, the movable roller 17 is rotatably connected inside the bracket 16, the movable roller 17 is located directly below the conveyor belt 4, and the top of the movable roller 17 contacts the conveyor belt 4. When an object passes on the conveyor belt 4, the movable roller 17 plays a certain supporting role on the conveyor belt 4, and at the same time, the movable roller 17 can also receive the pressure brought by the object and apply this pressure to the pressure sensor 15.

[0061] Among them, the bracket 16 and the movable roller 17 can be made of nylon or copper with relatively light weight, which has little influence on the pressure induction of the pressure sensor 15 and improves the reliability of pressure induction.

[0062] Specifically, referring to Figure 1 As shown in the figure, when the flower basket is conveyed on the conveyor belt 4 and passes above the movable roller 17, it means that the flower basket has reached the position. The movable roller 17 will receive the pressure brought by the flower basket. At this time, the movable roller 17 will apply this pressure to the pressure sensor 15. After the pressure sensor 15 senses the pressure change, the conversion circuit inside it will convert and generate an electrical signal, and send this electrical signal to the main control box 8, so that the main control box 8 controls the drive motor 2 to stop working, that is, the conveyor belt 4 stops running, thereby stopping the in-place induction of the flower basket.

[0063] In summary, referring to Figure 1 、 Figure 2 and Figure 7As shown in the figure, the through-beam photoelectric emitter 7, the through-beam photoelectric receiver 13, and the passive radiation sensor 10 are respectively used to sense the in-place state of the flower basket in the horizontal and vertical directions, so as to perform multi-dimensional in-place sensing on the flower basket. The pressure sensor 15, the bracket 16, and the movable roller 17 are used to sense the in-place state of the physical object of the flower basket. By combining multiple in-place sensing methods, the accuracy of the in-place sensing of the flower basket is greatly improved.

[0064] Refer Figure 1 、 Figure 3 and Figure 6 As shown in the figure, the pre-sensing component includes a diffuse reflection photoelectric sensor 12, and the diffuse reflection photoelectric sensor 12 is installed on one side of the through-beam photoelectric sensor. One side of the second vertical plate 9 is fixedly connected with an extended fixing plate 11, and the diffuse reflection photoelectric sensor 12 is fixedly connected to the extended fixing plate 11. The extended fixing plate 11 is fixedly assembled to the second vertical plate 9 by bolts, and the diffuse reflection photoelectric sensor 12 and the through-beam photoelectric receiver 13 are in the same horizontal plane. The diffuse reflection photoelectric sensor 12 and the extended fixing plate 11 can be fixed by means such as clamping and positioning plugging, which is convenient for disassembling, inspecting, and maintaining the diffuse reflection photoelectric sensor 12.

[0065] Specifically, refer Figure 3 As shown in the figure, by using the characteristic that the light emitted by the diffuse reflection photoelectric sensor 12 is reflected on the surface of the object, it is possible to determine whether the object exists by detecting the intensity of the reflected light, so as to realize the sensing of the flower basket. The diffuse reflection photoelectric sensor 12 is located on one side of the through-beam photoelectric receiver 13 and can sense the flower basket earlier than other in-place sensing components. When the diffuse reflection photoelectric sensor 12 senses that the flower basket is about to be in place, the internal conversion circuit will convert and generate an electrical signal. After the main control box 8 receives this electrical signal, it will control and reduce the power output of the drive motor 2 through the frequency conversion circuit, so as to slow down the rotation speed of the transmission shaft 3 and thus slow down the running speed of the conveyor belt 4, and further slow down the conveying speed of the flower basket on the conveyor belt 4 before it is about to be in place.

[0066] In this way, when the flower basket is in place, the flower basket will be conveyed to the in-place state at a slow speed, greatly reducing the deviation generated when the flower basket is in place during the response time of the in-place sensing component, and greatly improving the accuracy of the in-place position of the flower basket.

[0067] Refer Figure 1 、 Figure 3 and Figure 6 As shown in the figure, the two ends of the main body frame 1 are respectively detachably fixed with a first vertical plate 6 and a second vertical plate 9, and the first vertical plate 6 and the second vertical plate 9 are symmetrically arranged. Multiple groups of through holes are provided on the first vertical plate 6 and the second vertical plate 9, and fixing bolts 14 penetrate through the interiors of the through holes. Threaded holes matching the fixing bolts 14 are provided on the main body frame 1, and the first vertical plate 6 and the second vertical plate 9 are respectively locked and fixed to the main body frame 1 by the fixing bolts 14.

[0068] Specifically, refer to Figure 3 and Figure 6 As shown, the first vertical plate 6 and the second vertical plate 9 can be positioned and fixed by fixing bolts 14, ensuring that the first vertical plate 6 and the second vertical plate 9 can always be installed precisely and symmetrically. This facilitates the precise assembly of the through-beam photoelectric emitter 7 and the through-beam photoelectric receiver 13 on the first vertical plate 6 and the second vertical plate 9. In addition, the first vertical plate 6 and the second vertical plate 9 can be flexibly disassembled and assembled, which is convenient for regular disassembly, assembly, inspection and maintenance of the through-beam photoelectric emitter 7, the diffuse reflection photoelectric sensor 12 and the through-beam photoelectric receiver 13.

[0069] In this embodiment, the installation method of fixing the first vertical plate 6 and the second vertical plate 9 by fixing bolts 14 can be replaced by a positioning magnetic block and a positioning groove with a magnetic plate inside. Here, a set of positioning magnetic blocks are fixedly connected to the first vertical plate 6 and the second vertical plate 9 respectively, and a set of positioning grooves are opened at designated positions at both ends of the main frame 1. A set of magnetic plates is fixed inside the positioning grooves, and the positioning magnetic blocks and the positioning grooves are matched.

[0070] Specifically, when assembling the first vertical plate 6 and the second vertical plate 9, the positioning magnetic blocks on the first vertical plate 6 and the second vertical plate 9 are first inserted into the positioning grooves at both ends of the main frame 1. At this time, the positioning magnetic blocks on the first vertical plate 6 and the second vertical plate 9 will be attracted and fixed with the magnetic plates to achieve the fixing effect of the positioning magnetic blocks inside the positioning grooves, thereby realizing the assembly and fixing of the first vertical plate 6 and the second vertical plate 9. When it is necessary to disassemble the first vertical plate 6 and the second vertical plate 9 to inspect and maintain the through-beam photoelectric emitter 7, the diffuse reflection photoelectric sensor 12 and the through-beam photoelectric receiver 13, simply pull the first vertical plate 6 and the second vertical plate 9 outward with force to pull the positioning magnetic blocks out of the positioning grooves. This also facilitates the inspection and maintenance of the through-beam photoelectric emitter 7, the diffuse reflection photoelectric sensor 12 and the through-beam photoelectric receiver 13.

[0071] Working principle:

[0072] During installation, the through-beam photoelectric emitter 7 and through-beam photoelectric receiver 13 are pre-installed on the first vertical plate 6 and the second vertical plate 9 respectively. Then, the first vertical plate 6 and the second vertical plate 9 are assembled and fixed at both ends of the main frame 1. Next, the passive radiation sensor 10 and the pressure sensor 15 are assembled on the crossbeam 5 respectively. Finally, the corresponding circuits are connected.

[0073] In use, the diffuse reflection photoelectric sensor 12 performs pre-position sensing of the flower basket. After the diffuse reflection photoelectric sensor 12 senses the flower basket, the operating speed of the conveyor belt 4 slows down, so that the flower basket is conveyed to the position at a lower speed, improving the accuracy of the flower basket's position. When the flower basket is in position, the horizontal reverse position sensing of the flower basket is performed by the through-beam photoelectric emitter 7 and the through-beam photoelectric receiver 13, and the vertical reverse position sensing of the flower basket is performed by the passive radiation sensor 10, thereby realizing multi-dimensional position sensing of the flower basket. In addition, when the flower basket is in position, pressure is applied to the movable roller 17. After the pressure sensor 15 senses the pressure change, it can also perform physical position sensing of the flower basket. Thus, by combining multiple position sensing methods, the flower basket can be more accurately sensed to be in position.

[0074] This invention can pre-sense the flower basket before it arrives at its destination and reduce the running speed of the conveyor belt 4, thereby reducing the deviation in the arrival time of the flower basket and improving the accuracy of the flower basket's position. At the same time, it can perform multi-dimensional coordinated sensing of the flower basket's arrival to ensure accurate sensing of the flower basket's arrival and effectively avoid the occurrence of production accidents.

[0075] The foregoing description of specific exemplary embodiments of the invention is for illustrative and explanatory purposes. These descriptions are not intended to limit the invention to the precise forms disclosed, and it will be apparent that many changes and variations can be made in accordance with the foregoing teachings. The exemplary embodiments were chosen and described in order to explain the specific principles of the invention and its practical application, thereby enabling those skilled in the art to implement and utilize various different exemplary embodiments of the invention, as well as various different choices and variations.
